- Reykjavík + south Iceland: Coastal + volcanic trails.
Tier 2 — strong trail-running
- Edinburgh (Holyrood Park): Arthur's Seat + Pentlands.
- Bergen: Mt Ulriken + Fløibanen + 7 Mountain Hike.
- Granada (Sierra Nevada): High-altitude + mountain trails.
- Athens (Mt Hymettus): Surprisingly good trails 30 min from centre.
Tier 3 — niche trail-running
- Sarajevo (Trebević + Bjelašnica): Olympic mountains.
- Plovdiv (Rhodope mountains): 30 min south.
- Cluj-Napoca (Apuseni): Limestone trails.
